it is a crystal. a crystal has actually more than one flat surface. I dont really know how to explain andled sides but it kid of makes it look like an ice cream cone with a point at both the top and the bottom. the "cone" is actually several flat surfaces making it look roundish.
A Right-angled Trapezium
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.

The following shape has three sides and the only angles are right angles. ----- | |___
A Rhomb
A right angled triangle is an example of a shape with exactly 2 perpendicular sides.
A Right-angled Trapezium
A right angled triangle.
Rectangle.
A three-angled 2D shape is called a triangle. Triangles can be classified based on their angles as acute, right, or obtuse, or based on their sides as equilateral, isosceles, or scalene. Each triangle has three sides and three vertices.
a house shape: a floor, 2 parallel walls and an angled roof
A shape with three sides is called a triangle: 3 equal sides = equilateral 2 sides same length = isosceles 1 right angle = right-angled triangle
see if the shape has four sides if they have you have found the square Check if all 4 sides are of the same length and if the interior angles are all 90° (right angled)
A rectangle is a shape with four sides, and four right-angled corners.A square is with four sides of equal length, and four right-angled corners.Since the rectangle doesn't have any rules regarding the length of the sides, all sides could be the same length, and it would still be a shape with for sides, and four right-angled corners. Answer: The set of all shapes meeting the criteria for "Squares" is included in, but not convergent with, the set of all shapes meeting the criteria for "Rectangles"
A pentagon has 5 sides. A hexagon has 6 sides. The penta- prefix comes from the Greek for 5; The hexa- prefix comes from the Greek for 6. The -gon suffix comes from the Greek for "corner" or "angle". Thus a pentagon is a five cornered (or five angled) shape; and a hexagon is a six cornered (or six angled) shape.
The shape of 2D is a flat surface.
right angled triangle does not have all equal sides
